The
most known module is LTM or Local
Traffic Manager
which is useful for traffic
load
balancing.
The
BIG-IP version 13.1 has included new features like test button for
monitor, iRule execution tracing features for debugging, TCPDUMP
remote output, configuration load independent of licensing, etc. For
instance, we can check monitors
before assigning to nodes or pools, we
can know the time-consuming iRules and we can also mirror
traffic
to a remote analysis tool.

Test Button for Monitors

Another
interesting module is ASM or
Application Security Manager
which is useful to
defeat sophisticated and complex threats for protecting web
applications. The
BIG-IP version 13.1 has also included new features to this module
like simplified attack signature creation, remove inactive file
types, passive deployment policy template, brute force mitigation
improvements, etc. For instance, we can already write attack
signatures easily, we
can accept suggestion of removing inactive entities, we
can apply a fully transparent policy without interfering with traffic
and we can also improve brute force mitigation attacks by username,
IP addresses and device IDs.

Passive Policy Deployment Template

F5
BIG-IP ASM has different kind of
security policy templates which can be used for protecting Virtual
Servers. For instance, if we want to apply a negative
security policy where attack signatures detect and block known
attacks and where we don’t want to
configure manually entities such as file types, parameters, URLs,
cookies, redirection, etc, we can configure
a Rapid Deployment Policy which is easy to
accomplish this task.
